HONEYWELL CC-TCNT01 ControlNet IOTA Terminal Block

Description

Key Technical Specifications

Product Introduction & Supply Chain Strategy

The Honeywell CC-TCNT01 is a specialized non-redundant ControlNet I/O Termination Assembly (IOTA) designed for the Experion PKS Series C architecture. Functioning as the primary mechanical and electrical gateway for the ControlNet Interface Module (CC-PCNT01), the CC-TCNT01 connects Series C C300 controllers to legacy ControlNet field networks, PLC racks, and third-party subsystems. Equipped with twin BNC coaxial taps, it handles high-speed, deterministic peer-to-peer data transfers without burdening primary Ethernet backbones.

Securing the CC-TCNT01 as New Surplus inventory provides immediate hardware availability and eliminates long OEM production queues. This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability. Avoiding second-hand or worn mounting cards eliminates the risks of damaged BNC taps, loose grounding clips, and cracked carrier connectors. Keeping a verified New Surplus CC-TCNT01 on-site ensures quick recovery from physical cabinet accidents or field network electrical hits.

Installation & Configuration Guide

Stage 1: Pre-Installation (Prep & Safety)

1. Turn off power (LOTO) on the incoming 24 VDC feeder supplying the targeted Series C carrier channel.
2. Put on an anti-static wrist strap grounded to an unpainted chassis point to avoid ESD damage to sensitive communication circuitry.
3. Verify coaxial cable labeling (ControlNet Channel A and Channel B) and confirm proper 75-ohm termination resistors are available.

Stage 2: Removal

1. Loosen the top and bottom retaining screws on the CC-PCNT01 ControlNet module and carefully disconnect it from the CC-TCNT01 socket.
2. Unthread and remove the BNC coaxial cable connectors from the IOTA faceplate.
3. Unclamp the DIN rail retention latches or carrier screws, then lift the CC-TCNT01 assembly off the channel frame.

Stage 3: Installation (Clone & Seat)

1. Take the replacement New Surplus CC- base plate out of its static-shielding bag.
2. Mount the CC- onto the DIN rail or carrier track, locking it firmly into place.
3. Reattach the ControlNet Channel A and Channel B coaxial cable connectors onto the BNC taps, twisting to lock securely.

Stage 4: Power-On & Testing

1. Align the CC-PCNT01 ControlNet module with the card socket guides, push in firmly until seated, and tighten the retaining screws.
2. Restore 24 VDC power to the carrier assembly. Check that backplane bus voltages measure between 21.6 and 26.4 VDC.
3. Check Experion Control Builder and network diagnostic screens to confirm active ControlNet communication (OK LED steady green) with no media packet drops or noise errors.

Firmware/Software Versions & Upgrade Notes

• Passive Carrier Architecture: The CC- is a passive termination assembly without programmable microprocessors or onboard firmware. Compatibility is governed entirely by the mounted active ControlNet module (CC-PCNT01).
• Conformal Coating Variant: The CC- is the standard non-coated version. For corrosive processing environments requiring ISA-S71.04 Class G3 compliance, choose the conformal-coated variant (CC-TCNT51).
• Redundancy Selection: The CC- is designed for single-module execution. If redundant ControlNet module pairs are required for high-availability communication loops, use the redundant IOTA variant (CC-TCNT11 or CC-TCNT61).
• Physical Keying: The socket layout is keyed specifically for ControlNet interface hardware. Do not attempt to mount standard Analog or Digital I/O cards into the CC- slot.

Frequently Asked Questions (FAQ)

Q: This unit is offered as New Surplus. How can I confirm it is not used or refurbished?

A: This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability. Our inventory comes directly from surplus project holds, canceled plant expansions, and official spare stocks. Every base features pristine BNC contacts, intact circuit traces, factory tags, and zero operating time.

Q: How does your pricing compare to buying factory-direct from Honeywell or an online broker?

A: Our pricing reflects the cost of securing genuine New Surplus inventory globally. It may be 20–30% higher than a refurbished gamble, but it is substantially less than OEM list prices, and it buys you 100% peace of mind. You avoid long factory lead times while eliminating the risks of worn BNC jacks and loose mounting tracks common in used parts.

Q: What is the main difference between CC- and CC-TCNT51?

A: Both assemblies feature the same physical socket structure, BNC connector configuration, and mounting dimensions. The distinction is environmental protection: CC-TCNT51 features heavy-duty conformal coating for ISA Class G3 harsh environments, whereas CC- is non-coated for standard control cabinets.

Q: Can I hot-swap the CC-PCNT01 module mounted on this CC- assembly?

A: Yes, the active CC- module supports Removal and Insertion Under Power (RIUP). However, replacing the underlying CC- base plate requires powering down the carrier rack and disconnecting coaxial lines.

Q: What warranty and quality verification process do you provide with this module?

A: We provide a full 1-Year functional replacement warranty with every CC- assembly. Prior to shipment, each IOTA undergoes BNC continuity testing, pin insulation checks, and visual mechanical inspection to ensure plug-and-play installation readiness.
